There are two notable differences with L28ET manifolds. One version has a 'forward' location of the turbo, the other version has a 'rearward' location of the turbo. Also there is a Euro Manifold, which has 1 5/8" runners and a hole for the turbo that doesn't have a big bump restricting flow to the scroll. ___________________________________________________________________________________________________________________________________________________________________
